VACHERON CONSTANTIN OVERSEAS SKELETON
Overseas Skeleton references expose the architecture and hand finishing of Vacheron Constantin’s ultra-thin openworked calibres. The best-known executions combine a perpetual calendar with calibre 1120 QPSQ in a 41.5 mm precious-metal sports case and interchangeable bracelet-and-strap system.

Model History & Buyer Guide
Overseas Skeleton: Openworked, Ultra-Thin, and Calendar-Critical
The Movement Becomes the Dial
Overseas Skeleton references remove much of the conventional dial to expose bridges, wheels, calendar work, and hand finishing. The best-known modern examples are Perpetual Calendar Ultra-Thin Skeleton watches using calibre 1120 QPSQ.
They retain the Overseas case language and interchangeable wearing system but are not substitutes for the 150 m Selfwinding sports model. The 41.5 mm perpetual-calendar skeleton is rated to 50 metres and should be treated as a high complication.
Legibility and Condition
Openworking makes finishing visible but can reduce quick legibility. Applied markers, contrasting hands, and the sapphire dial elements should be checked under several lighting conditions.
Scratches on the crystal, contamination, damaged blackened surfaces, or calendar misalignment are harder to hide than on a closed dial. Factory service history and a complete bracelet/strap set are particularly valuable.

|---|---|---|---|
| 4300V/120R-B547 | Pink-gold Perpetual Calendar Ultra-Thin Skeleton | $105,000 — $145,000 | Bracelet and full strap set affect value |

Understanding Overseas Skeleton
Skeleton is a curated Overseas subset: movement type and calendar architecture still define the exact watch.
| Feature | Function | Why It Matters |
|---|---|---|
| Calibre 1120 QPSQ | Ultra-thin automatic perpetual calendar | Combines a 22k peripheral-style rotor architecture with openworking |
| Openworked bridges | Expose the movement and calendar train | Finishing and contamination are directly visible |
| Quick-change system | Switches bracelet and straps | Preserves Overseas versatility in a high complication |
Reference-Level Buying Checklist
Use the exact reference—not the family name alone—to verify the following points before purchase.
| Check | What to Verify | Why It Matters |
|---|---|---|
| Exact complication | Perpetual calendar versus tourbillon or another skeleton calibre | Openworked appearance alone does not identify the movement |
| Calendar | Leap year, day, date, month, moon, and safe setting | Misuse can damage an ultra-thin mechanism |
| Visible movement | Scratches, dust, corrosion, screws, and finish consistency | Openworking exposes evidence of poor handling |
Frequently Asked Questions
About Overseas Skeleton
Is every Overseas Skeleton a perpetual calendar?
No. The famous 4300V references are, but Vacheron Constantin also produces other openworked Overseas complications such as tourbillons.
Can it be worn like a standard Overseas?
It offers the changeable strap concept, but water resistance and mechanical delicacy differ. Follow the exact reference rating and service guidance.
Why can two skeleton references have very different prices?
Movement, complication, metal, bracelet, production, condition, and included strap system can differ even when the overall case design looks similar.
